CHURN.

SPEGIFIGATION formingpart of "Letters Patent Nd. 692,182, dated January28, 1902.

Application filed April 11. 1901.

To all whom, it may concern;

Be it known that I, JAMES S. FITZHUGH, a citizen of the United States,residing at Waco, in the county of McLennan and State of Texas, haveinvented certain new and useful Improvements in Ohurns; and I do herebydeclare the following to be a full, clear, and exact description of theiuvention,such as will enable others skilled in the art to which itappertains to make and usethe same.

My invention relates to improvements in churns and provides especiallyfor a churn which is automatic in its action, requiring no furtherattention during the churning process other than to stop or start theoperation of the device when it is desired to inspect the progress offormation of the butter. j

To this end I have devised a churn which operates substantially in themanner of a pendulum,and to more fully describe myinvention referenceishad to the accompanying drawings, in which like parts are designatedby the same letters throughout the several views.

Figure 1 represents a sectional elevation of my device on the line 1 1of Fig. 2. Fig. 2 is a side elevation looking at the right-hand side ofthe device as shown in Fig. 1. Fig. 3 is a back View of the device, thelower portions being broken away; and Fig. tis a sectional view takenlongitudinally through the churn.

A represents a framework composed of the front uprights A and the rearuprights A provided at their upper ends with the crosspieces B B andconnected together by the transverse pieces 0 C. To these top pieces B BI-suspend a laterally-swinging arm D in any suitable manner, butpreferably as shown in the drawings, where the arm D is mounted on aspindle d,pivotally supported by the depending bearing-brackets d. Thearm D is provided with a suitable escapement device E,which alternatelyengages with the teeth of a pair of escapement-wheels F F, suitablymounted on a pair of shafts ff, supported by the bearings f f secured tothe front and-rear uprights of the frame A. The escapement-wheels F Fare driven in any suitable manner-as, for instance, by the ordinaryclockwork mechanism. In the drawings, however, I have shown a pair ofcogwheels G G, the cogs of which mesh with each Serial in. 55,392. (Nomodel.)

other and engage with the teeth of a pair of smaller cogs g 9', carriedby the shafts ff at the opposite end from the escapementwheels. One ofthese cogwheelsG is mounted on the shaft 9 which also carries a drum H,adapted to receive a coil of rope or chain h, suspending a weight I. Thedrum H is provided with the ratchet-wheel h, which is in engagement withthe usual pawl 7'1. on the cog-Wheel G for locking the roller or drumfrom backward movement while the rope or chain is being wound up onsame. The ordinary means J to receive a crank is provided on the end ofthe shaft g for winding up the weight. By the above construction thenecessary means for imparting motion to the Working parts is procured;but it is evident that instead of using the weight and drum a'nyothersuitable mechanical means maybe applied, as before suggested.

To the lower end of the arm D, I suspend the churn K, preferably-of thebarrel shape, as shown, and provided with the handle 76, which handle issuitably connected, as at k, to the arm D. On the upper surface of thechurn I provide a circular orifice L, and in said orifice is snuglyfitted the annular rim portion L, provided on its exterior surface withscrew-threads Z to receive the screwthreaded cap M. In the cap M, I haveshown a glass peep-hole m, through which the contents of the churn caneasily be inspected. In order that any gases which might accumu latewill readily be carried olf, I have provided the tube N, of glass orother suitable material. I have also provided the exterior surface ofthe churn with the short legs 0, upon which the churn sets when detachedfrom the pendulum-arm. The transverse cross-pieces O of the frame are sosituated in relation to the churn as to be in the path of the lateralswing of the churn, and upon these cross-pieces I provide the buffers P,of rubber or other suitable resilient material. These buifers serve thetwofold purpose of jolting the churn at the end of its stroke, therebysloshing the contents for creating the necessary churning action, andforming a rebounding cushion for assisting in overcoming the effect ofgravity on the swinging churn.

Instead of placing the buffer-blocks on the transverse cross-pieces itis evident that I might locate the same on the end faces of the churn,as shown at P, or I may use them both on the churn and cross-pieces asmay be desired.

I do not wish to limit myself to the precise construction as describedabove, as it is obvious that various changes might be made in the abovedevice without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, :is-

In a pendulum-churn,tl1e combination with the frame, of a bracketmounted in the upper portion of said frame, a depending arm pivotallymounted'in said bracket, escapement-
